B4J Question other behavior Regex.IsMatch("[\d\w]+", text) in b4j and b4a

[schimanski]

In b4j, the code works correct for me and filterd 'ä, ö, ü'.
In b4a it doesn't...

If Regex.IsMatch("[\d\w]+", tf1.Text) = False

What exactly are you trying to implement?

 

[schimanski]

I tried to check a textfield, if the text doesn't contains illegal characters for an URL....

Use this pattern: [A-Za-z0-9_]+

The Android implementation is actually more correct in this case.
